Transient mud cracks can promote plant survivorship by trapping seeds, and enhance germination and growth by increasing water infiltration in the soil, thus facilitating the formation of a persistent salt marsh landscape. Cracks can help the salt marsh withstand more intense droughts, leading to postponed collapse and faster recovery. They are horizontally bedded casts, which are kind of rare, as usually vertical worm burrow casts are all that are found in this area. They were originally thought to be Calamites roots, a proto tree, but roots taper and these fossils show no evidence of taper.

Nov 17, 2016 · Mud cracking is a coating flaw that occurs on the surface of a wall that looks similar to deep and irregular mud cracks on the surface of the earth. This phenomenon occurs when an over coating is applied on curved surfaces and unprepared surfaces. It is common along corners where there might be an accumulation of paint.

Mud cracks form when a shallow body of water (e.g., a tidal flat or pond), into which muddy sediments have been deposited, dries up and cracks (Figure 6.24). This happens because the clay in the upper mud layer tends to shrink on drying, and so it cracks because it occupies less space when it is dry.Nov 1, 2006 · 2.
